CHINO HILLS -- Dozens of residents crowded into the Grand Avenue Park Community Center on Thursday night to voice their concerns over a so-called maternity hotel reportedly operating in their city.

"We don't want this in our community," said Rossana Mitchell, who led the meeting hosted by Not in Chino Hills, a grass-roots community group.

The group had just protested the alleged Chinese maternity operation housed in a large hilltop home at 15250 Woodglen Drive at a demonstration over the weekend.

San Bernardino County sheriff's Capt. Bill Lenew said the Woodglen home does appear to house pregnant women on a temporary basis as does a nearby apartment complex.

Mitchell identified the apartment complex at the meeting as the Green Valley Apartments, 14901 Frost Ave.

One woman advocated contacting Randall Lewis, executive vice president of Lewis Operating Corp., which owns the Frost Avenue property, in order to "hit him in the wallet."

"We haven't heard of any problems with this situation," Lewis said Monday.

For privacy reasons, Lewis declined to talk about the tenants of the apartments.

Mitchell, who is running for a seat on the City Council, urged residents to start a letter-writing campaign to local newspapers, council members and even to President Barack Obama.

"We should write to the Chinese newspapers," said Kelly Good, a 20-year resident of Chino Hills. "Maybe in this way it would shame them because, you know, of their culture."

At least one person at the meeting, saw nothing wrong with what the pregnant women were doing.

"They're coming over legally on visas and having their babies here," said Mike Cargile of Pomona. "They found a loophole and they're exploiting it while it exists. This country is at war with anyone that finds a loophole."

Cargile went on to say that Pomona, a sanctuary city, would gladly take those mothers who would like to have their children born in the United States.

Some people, though, became concerned over more invasive tactics advocated by the group and Mitchell, including asking stay-at-home mothers to sign up for shifts to locate and follow mini vans she claims are part of the maternity hotel.

"We have a flier with a picture of a Mercedes mini van that is associated with this mansion," Mitchell said, passing out a flier with the image of the van and its license plate on it.

Earlier in the week, Mitchell, along with Alexander Ramirez with ComCam, a surveillance company, visited a resident who lived near the mansion. They discussed how a camera system could be placed on the homeowner's property while still filming vehicle activity on a street leading up to the Woodglen home.

The group plans to be at the next City Council meeting, to be held at 7 p.m. Tuesday at City Hall, 14020 City Center Drive.
